This city of 35,163 inhabitants was founded between 1811 and
1814. The official flag of San Lorenzo is a systematic reduction
of the Coat of Arms of the Muñoz [Mun~oz] de Oneca family,
founders of the town. Thanh-Tâm Le, 12 January 1999

The colors gold and red have been chosen for Coat of Arms of
San Lorenzo, because they are the colors of the Muñoz lineage
shield, from which Don Valeriano Muñoz de Oneca belonged to,
founder of the town of San Miguel de Hato Grande, today San
Lorenzo. The grill is the traditional symbol of San Lorenzo,
deacon and martyr, patron of the town, because in a grill he
underwent the martyrdom, slowly burned to death. The hill or
mountain represent the Gregorio Hill, which dominates the San
Lorenzo panorama. The cross is one of the heraldic attributes of
San Miguel Arcángel, whose name was given to the town in the
begining. Source: <www.linktopr.com>.Nelson Román, 28 July 2004
